Then why not play Benhart now? Not disagreeing with you. If he truly is the next Rimington (or close) then play him, but do the same with the other guys as well.
Kind of like Holgorsen at Houston. Asking his starting WR and WB to redshirt (after starting in and playing 4 games) as the season sux and they'll be better next year. Barring some miracle, I do not think Frost and Co feel like we will win the West. So why not play the young guys for the experience. Without the experience, next year will be a lot of the same excuses. The team is young, inexperienced, new to the scheme, another year of S&C. Get them the playing time now. Let them play a good amount of snaps in at least 4 games. Spell the starters for the stretch. Like Hickman today, is he burning his shirt for ST's? Taylor-Britt returning punts after JD was out?
Build the future today.
